I'm in the middle of a LONG problem and came across a part where I need to do this integral:

integral of: e^[(cos(t)-t)/5]

Please help!

I'm pretty sure you need to solve this numerically. Is that acceptable for the problem?

It's very amusing to consider instead the function
[tex]
e^{-t/5}
[/tex]
It looks almost just like your function but with a few less little "fine structure" wiggles.

The integrals of both functions should be rather similar. For example
[tex]
\int_0^{\infty} e^{(-t/5)}=5
[/tex]
whereas
[tex]
\int_0^{\infty}e^{(Cos[t]-t)/5}\approx 5.09
[/tex]
